    ARDUINO

                      Arduino is a small electronic board that can follow instructions to control things like lights,
                      motors, sensors and more. It is like a tiny computer that helps you build smart devices. You
                      write code and the Arduino board reads it and makes things happen—like turning on a light or
                      moving a robot.
                      The following are the types of Arduino boards:

                          Arduino Uno: Arduino Uno is the most popular and beginner-friendly
                         board.  It is easy  to  use and perfect  for  simple  projects  like  blinking
                         LEDs, sounding buzzers or building a basic circuit. Most students start
                         learning Arduino with this board.

                                                        Arduino  Nano:  Arduino  Nano  is  a  smaller version  of  the  Uno.
                                                       It works the same way but is tiny, which makes it perfect for small
                                                       or portable projects. It can also fit on a breadboard, which helps
                                                       in building neat and compact circuits.

                          Arduino Mega: Arduino Mega is larger and more powerful than Uno.
                         It has more memory and more pins, which means you can connect
                         many sensors, motors or displays at once. It is often used in bigger
                         projects like robots or home automation systems.

                                                Arduino Leonardo: Arduino Leonardo is special because it can act like a
                                               computer keyboard or mouse. This means you can use it to build devices
                                               that control your computer with buttons or sensors, like making your own
                                               game controller.

                          Arduino  LilyPad: Arduino  LilyPad  is  a  round  and  soft  board  designed
                         especially for wearable projects. You can sew it onto clothes and connect it
                         with special thread instead of wires. It is perfect for making smart clothing,
                         light-up costumes or wearable gadgets.

                      In Tinkercad, Arduino is a virtual version of the real Arduino board. It allows you to build and test
                      your electronic projects on a computer screen, without using real wires or parts.

                             COMPONENTS OF ARDUINO UNO

                      The Arduino Uno is a versatile board that controls devices, reads sensor data, provides power
                      and enables interaction through input and output connections.
